Principal component analysis (PCA) of the BP treatment. Dotted and solid circles in score plots indicate 95% and 99% confidence intervals for all plots, respectively. Colored circles indicate 95% confidence intervals for each group; (A) primary polyps without zooxanthellae; (B) primary polyps with zooxanthellae. PC1, first principal component; PC2, second principal component; BP, BP treatment, C, control and S, zooxanthellae present.
